BEENFORCING FRAME FOR CONCRETE BUILDING STRUCTURES.

Application filed March 18, 1922. Serial No. 544,769.

To all whom it may concern:

Be it known that I, MANsoUR SAMAHA, a citizen of the United States,residing at Atlantic City, in the county of Atlantic and State of NewJersey, have invented new and useful Improvements in Reenforcing Framesfor Concrete Building Structures, of which the following is aspecification.v

The invention relates to a reenforcing frame for concrete buildingstructures.

The object of the present invention is to improve the construction ofreenforcing frames for concrete building structures and to provide asimple and comparatively inexpensive reenforcing frame adapted to form ametallic casing for the concrete and capable of providing inner andouter exterior skins arranged in spaced relation to permit the concreteto flow through the en tire reenforcing frame and form a mono lithicconcrete structure within the said metallic. casing.

A further object of the invention is to provide a reenforcing frame ofthis character adapted to present at the inner and outer skins of themetallic casing exterior plane wall surfaces adapted to be finishedinteriorly and exteriorly of the building in any desired manner such asby painting, enameling or otherwise coating or decorating such exteriorplane surfaces.

A further object of the invention is to provide a. reenforcing frameadapted to form supporting columns of the concrete either as a portionof the walls or at points within the structure spaced from the walls andcapable also of providinggirders at the ceiling or roof of the structureas required.

Another object of the invention is to pro- -vide a reenforcing frameadapted to constitute a mold or form into which the concrete is pouredand capable of constitutinga permanent reenforcing means for theconcrete structure and thereby save time, labor and material inobviating the necessity of providing temporary forms or frames formolding the concrete.

. It is also an object of the invention to provide a reenforcing framecomposed of metallic sections adapted to be easily and 'rapidlyassembled into areenforcingframe of the required character by unskilledlabor and thereby lessen the cost of erecting concrete structures.

With these and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings and pointedout in the claims hereto appended, it being understood that variouschanges in the form, proportion and minor details of construction,within the scope of the claims, may be resorted to without departingfrom the spirit or sacrificing any of the advantages of the invention.

In the drawings, in which like characters of reference designatecorresponding parts in the several figures Figure 1 is a verticalsectional view of a portion of a concrete building provided with areenforcing frame constructed in accordance with this invention.

Figure 2 is a vertical sectional view of the reenforcing frame takenlongitudinally of one of the walls before concrete is poured.

Figure 3 is a transverse sectional view of the same extending throughthe portion of one of the walls and one of the ceilings.

Figure 4 is a vertical sectional view of the ceiling taken at rightangles to Fig. 3, the concrete being omitted.

Figure 5 is ahorizontal sectional View through the wall frameillustrating the arrangement of the wall. sections and the columnsections. I p

Figure 6 is a detailperspective view illus' trating the construction ofthe sections.

Figure 7 is a detail sectional view show ing the terminal flanges of thesections so cured together.

Figure 8 is an enlarged detail view of the rod and clamping portions.

In the accompanying drawings,.in which is illustrated the preferredembodiment of the invention the reenforcing frame which consists ofinner and outer metallic skins at the walls,.partitions and otherupright concrete portions of a building provides between the inner andouter skins a continuous space extending throughout the said walls,

n'oerlv soaced from each other.

section consists of a metallic shell composed of a plate or web 5 andupturned or inturncd side and end flanges 6 and 7. The sections may beof any desired form and of any required dimensions, but they arepreferably of oblong formation as illustrated in the accompanyingdrawings. The sections which are of box-like formation simulate wallblocks and are adapted to be arranged one upon anotherand built up toprovide inner and outer skins of therequired area and the abuttingflanges ot the sections are provided wit-h openings Shaving innerinclined edges 9 andadapted to receive terminal connecting and clampingportions 10 tions provided with heads which are passed through theregistering openings 8 at the enlarged ends thereof and are forced tothe reduced or narrow ends thereof by the blow of ahammer or othersuitable means whereby the abutting flanges are fairly clampetogether-and the inner and outer skins are In this manner, the sectionsof each skin are securely and quickly tastenedtogethcr while thesections-ot the opposite skins are positively tied together in accuratespaced relation. The inner edges of the flanges ot the sections of theopposite'skins are spaced apart to provide a solid central concrete wallformation 12 of the required thickness and the flanges 6. and 7 may beof any desired width to form recesses or enclosed spaces 13 for theconcrete to intelock the same with the sections. The transverse rods ormembers which clamp the sections together and connect the sections ofthe opposite skins also form reentorcing elements for the concrete andif desired additional reenforcing elements of any well known form andapproved construction may be incorporated in themonolithic concreteformation between the inner and outer skins where from the size andheight of a building such elements are deemed desirable or necessary.The inclined edges 9 of the-openings 8 form a longitudinally taperedopening which has suflicient width at one end to permit the engagingends of the connecting bars. or members to be readily passed through itand the heads or engaging portions of the rodsor members 11 are ofgreater size than the reduced portions of theslotsr. so as toeitectually prevent the angularly related terminals from being withdrawnthrough the said reducedportions ot the slots or openings. Anyothersuitable fastening meansmay however. be employed for connecting andclamping the sections in proper spaced relation.

. The walls. may. be provided at. suitable in .tcrvals with oilset orprojecting column sections 14: which form interior spaces 15communicating with the space 1- between the skins of the wall to formcolumns of the required size at the desired intervals integral with theconcrete monolithic structure. The inwardly ofi'set projecting columnsections which are arranged one upon another as shown consist of shellsoi? substantially the structure of the wall shells and the said shellspresent outer plane wall or column surfaces similar to the exteriorfaces of the sections of the inner and outer skin.

The partitions of a lniilding will be constructed similar to the wallsand as a partition would correspond in structure with an end walldetailed illustration of the same is believed to be unnecessary as itwould constitute mere duplication of the wall structure.

The horizontal elements of the concrete structure, namely; the'ceilingor root, stairways and the like require only a lower supporting skin,constructed of sections similar to those heretofore described andadapted to support the concrete so that the concrete ot the ceilings orroo'i or the like, will form an integral part of: the monolithicstructure of the building. This lower skin may be tlat, arched or of anyother required shape and the said lower skin 17 is provided at intervalswith downwardly offset girder sections 19. corresponding with the offsetcolumn sections and forming interior spaces 20 in the same manner thatthe spaces 15 within the columns are formed, so that the entire concreteof the building will constitute a single or monolithic concretestructure encased within the said metallic skins which present planeexterior surfaces for finishing or coating in any desired manner. Inuniting thesections of the skin with the sections of the vertical innerskins, the terminal flanges of thesections of the horizontal skins maybe bent backward or reversed to provide attaching portions 21; foroverlapping the sections of the inner vertical skins.

The sections may be provided wherever desired with suitable apertures 220t asize to permit escape of moisture without permitting the passage ofthe concrete therethrough.

Also the frame may be provided at any suitable points with the interior.columns formed by sections similar to those*here totore described andprovided with vertical interior-spaces 24. which communicate with thespaces between the upper and lower skins of the ceilings to permit theconcrete to :Work iszerected and the concrete is :poured and then thesecond story frame is set up and the concrete poured and so on until thebuilding is completed.

The invention is applicable to various reenforced concrete structuressuch as buildings, bridges and analogous constructions where amonolithic concrete structure and an exterior metallic protecting andreenforcing casing, in contra-distinction to the present interiorreenforcing means, are desired.

What is claimed is:

1. A concrete structure, including an exterior metallic casing composedof opposite skins comprising box-like sections having upturned flanges,provided with tapered openings presenting inclined edges, said sectionsbeing fitted together in staggered relation simulating wall blocks,interconnecting rods having headed terminal portions bent at rightangles and arranged in the tapered openings and engaging the inclinededges thereof to draw the sections together, and a. plastic fillingpoured between the sections of the opposite skins.

2. A concrete structure, including inner and outer skins composed ofbox-like sections having upturned flanges, said sections being fittedtogether in staggered relation simulating wall blocks, offsettingprojecting column sections connecting spaced sections of the inner skinto form columns, interconnecting rods engaging the flanges of thesection and holding the latter together, and a plastic filling pouredbetween the inner and outer skins.

3. A concrete structure, includin inner and outer skins composed ofbox-llke sections having upturned flanges, said sections being fittedtogether in staggered relation simulating wall blocks, interconnectingrods secured at their terminals to the flanges of the sections andholding the latter together, a lower ceiling skin composed of horizontalbox-like sections having upturned flanges fitted together simulatingblocks, said ceiling skin being secured to and supported by the saidinner skin, downwardly projecting offsetting beam sections connectingspaced sections of the ceiling skin, and a plastic filling pouredbetween the inner and outer skins and over the ceiling skin.

4:. A concrete structure, including inner and outer skins composed ofbox-like sections having upturned flanges, said sections being fittedtogether in staggered relation simulating wall blocks, interconnectingrods secured at their terminals to the flanges of the sections andholding the latter together, a lower ceiling skin composed of horizontalbox-like sections having upturned flanges fitted together simulatingblocks, said ceiling skin being secured to and supported by the saidinner skin, and an inner column consisting of connected sides enclosingan inner space and composed of box-like sections having inturned flangesand arranged upon each other simulating blocks, and a filling of plasticmaterial poured between the inner and outer skins and over the ceilingskins within the space enclosed by the column sections.
